Clear Aligners (Invisalign & Spark)

Smile Centrum's orthodontic team offers clear-aligner treatment with both Invisalign and Spark systems at its Prague branches, with Spark courses starting from 28,990 Kč. Treatment begins with an orthodontic examination and a 3D digital intraoral scan — no impression putty — from which an individual movement plan is built. Patients receive a series of custom transparent aligners that progressively guide teeth into position without metal wires, and attend check-ups approximately every three months. The approach suits adults and teenagers with mild to moderate bite and alignment issues who want a removable, nearly invisible alternative to fixed braces, and the network's long opening hours (07:00–19:00 on weekdays at most branches) make appointments easy to fit around work.

Clear aligners straighten teeth using a sequence of removable, custom-made transparent trays, each worn for about one to two weeks and exchanged for the next in the series as teeth gradually shift. Smile Centrum offers two established systems — Invisalign, the most widely used aligner brand globally, and Spark, a TruGEN-material aligner known for its clarity and stain resistance — allowing the orthodontic team to match the system to the case and budget. **How treatment works at Smile Centrum:** 1. *Consultation:* the orthodontic team examines your teeth and bite, evaluates suitability, and proposes a treatment plan. 2. *3D digital scan:* an intraoral scanner captures precise digital impressions — no impression material is used, which most patients find far more comfortable. 3. *Individual plan:* the digital model is used to design the full tooth-movement sequence and estimate the number of aligners and treatment duration. 4. *Aligner wear:* you receive sets of aligners with wear instructions (typically 20–22 hours per day, removed for eating and cleaning). 5. *Check-ups:* progress reviews approximately every 3 months — fewer visits than with fixed braces. **Advantages over fixed braces:** aligners are nearly invisible in everyday contact; they can be removed for meals, tooth brushing and important occasions; there are no dietary restrictions; comfort is higher with no wires or brackets to irritate the cheeks; and oral hygiene is much easier to maintain throughout treatment. **Suitability:** clear aligners at Smile Centrum are recommended for adults and adolescents with mild to moderate malocclusion — crowding, spacing, and many bite discrepancies. More complex cases may be advised toward alternative approaches at the consultation. **Pricing:** Spark treatment is published from 28,990 Kč in the network's 2026 price list; Invisalign is quoted individually after the scan based on case complexity. As a comparison point, full clear-aligner courses in Western Europe commonly run €3,500–€5,500, so Prague pricing from roughly €1,150 for Spark represents a significant saving for cross-border patients — and Smile Centrum's four-language patient service (Czech, English, Ukrainian, Russian) makes the process straightforward for international visitors. **Aftercare:** as with all orthodontic treatment, retention (retainers or a fixed retention wire) is needed after the active phase to hold the result; the team advises on retention options at the end of treatment.
